In collaboration with dancer and choreographer Jessy Tuddenham, we did a work for dancer, live video and sound. The performance involves a dancer isolated in a booth and performing a 2-minute choreography five times. The audience is presented with a video transformation of the dance that changes its perspective with each repetition. The transformations are performed in real-time by ali using a sensor-based instrument. This is the first of a series of three works for dance, video and sound.
